US Patent 7812536 Sealed opposed discharge plasma display panel

A plasma display panel including a front substrate, a rear substrate and intermediate barrier ribs defining discharge cells and having sustain electrodes located within the intermediate barrier ribs. A space is located between the front substrate and the rear substrate and includes an emissive area and a non-emissive area about emissive area. The emissive area has a fluorescent layer within. In the non-emissive area, an epoxy compound seals the emissive area from the outside, thus improving the sealing efficiency of the plasma display panel.
